When you turn on the tap in the Washington, DC area, your water may look clear—but that doesn’t mean it’s perfectly clean. Local water supplies often contain high levels of chlorine, "forever chemicals" (PFAS), and minerals that cause hard water. Fortunately, there are several water filtration options that can help improve the taste, smell, and safety of your home's water.
Here’s a quick breakdown of the most common types of home water filters, what they’re best for, and why DC-area homeowners trust Vito Services to help them choose and install the right one.
1. Carbon Filters (Activated Carbon / Granular Carbon)
Best for: Removing chlorine, bad tastes, and odors
Why: DC-area water utilities use chlorine and chloramine to disinfect water. While effective, these chemicals can leave behind strong odors and unpleasant tastes.
Activated carbon filters are excellent at removing these chemicals.
Where They’re Used:
Vito Tip: Look for a carbon filter certified to remove chloramine—not just chlorine—if your water company uses both.
2. Reverse Osmosis (RO) Systems
Best for: Producing ultra-pure drinking water
Why: RO filters use a multi-stage process to remove up to 99% of contaminants,
including lead, fluoride, PFAS (forever chemicals), and other dissolved solids.
Where They’re Used:
Vito Tip: RO systems usually include a carbon pre-filter, which also removes chlorine, making them a great all-in-one option for taste and safety.
3. Water Softeners
Best for: Combatting hard water and its effects
Why: Hard water in the DC area leaves behind limescale, soap scum, and buildup that clogs fixtures and damages appliances. Softeners replace calcium and magnesium (the “hard” minerals) with sodium or potassium ions, softening the water.
Where They’re Used:
Vito Tip: Combine a softener with a sediment or carbon pre-filter for the best overall water conditioning solution.
4. Whole-House Filters (Multi-Stage Systems)
Best for: All-around water quality improvements
Why: These systems can be customized with carbon filters, sediment traps, softeners, and more—offering a layered defense against everything from chemicals to hard minerals.
Where They’re Used:
Vito Tip: These systems are great for families who want to improve both drinking water and the water they use for bathing, cleaning, and laundry.
5. Filters for PFAS / “Forever Chemicals”
Best for: Reducing PFAS contamination
Why: PFAS (per- and polyfluoroalkyl substances) are persistent chemicals found in water across the country—including DC—and linked to health issues. Not all filters remove them, but high-performance carbon filters and RO systems have shown effectiveness.
Where They’re Used:
Vito Tip: Look for filters tested and certified to remove PFAS—many off-the-shelf filters are not.
